MEDIUMBootstrap Cross-Site Scripting (XSS) vulnerability for data-* attributes
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

bootstrapnpmDescription
A security vulnerability has been discovered in bootstrap that could enable Cross-Site Scripting (XSS) attacks. The vulnerability is associated with the data-loading-text attribute within the button plugin. This vulnerability can be exploited by injecting malicious JavaScript code into the attribute, which would then be executed when the button's loading state is triggered.
Affected Packages

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for bootstrap. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of bootstrap has shipped for GHSA-vxmc-5x29-h64v yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-vxmc-5x29-h64v is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-vxmc-5x29-h64v. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-vxmc-5x29-h64v in your dependencies?
O3 detects GHSA-vxmc-5x29-h64v across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
